Keeping this in consideration, why is ammonia used as fertilizer?
Ammonia is manufactured in the soil by organisms when organic fertilizer is used to increase soil fertility. Organic fertilizer, with its natural waste products, supports the growth of the billions of microorganisms that produce ammonia, which is then converted to the essential nutrient, nitrogen.
Secondly, is ammonia bad for plants? Although ammonia is essential to healthy plant growth, too much of a good thing can result in death. Plants may exhibit ammonia toxicity in the form of burnt leaves, blackened roots or even death. Ammonia also may enter the soil around plant roots from chemical fertilizers that contain ammonium (NH3 or NH4+).
Hereof, why ammonia is not used as a fertilizer?
Unfortunately, pure ammonia in solution is not typically an effective source of nitrogen when applied to the soil. Salts of ammonium are not volatile (like NH3, ammonia) and are unlikely to be lost through leaching of the soil (like nitrate), so are popular as a component of nitrogen fertilizer.
Why is ammonia toxic to plants?
Toxicity occurs when ammonium has built up to excessive lev- els in the substrate and plants absorb harmful amounts of it. Luckily, under normal growing conditions of warm temperatures and a well-aerated substrate, ammoniacal nitrogen forms are con- verted to nitrate by naturally occurring bacteria called nitrifiers.
